RE: [PSUBS-MAILIST] K-350 Reinforcing Rings

["Smyth, Alec" <Alec.Smyth@compuware.com>]

Snoopy is a K-250, not a K-350. The two designs have different stiffeners; the 250 uses an L section and the 350 uses a T. The T is not only stronger, it is also easier to fabricate. So if I were building any sub I would recommend T stiffeners.

Hi All.

Quick question regarding K-350 reinforcing rings.

Finally i've managed to get somewhere with ordering all my K-350 parts.  I have a company in the UK that have given me a quote and been very helpfull.  http://www.air-receivers.co.uk.  £2550 for all the basic parts, which is suprisingly well within my budget, and another company here in Guernsey Channel Islands that i'm waiting for a final quote.

Before i place my order though, i wanted to ask about reinforcing ring design.  The plans show a "T" bar shape welded to the hull at the bottom of the T.  However i watched the PSUBS convention talk by Dan H when he built "Snoopy" and he used a diferent shape and most subs that ive seen all seem to have square "n" shaped bar.

Are any of these other shapes better/safer?  Or shall i just stick rigidly to the design?

Thanks all.
James
